Industrial Process Heat Applications of Solar Energy
Concentrating solar collectors of low concentration ratio can supply hot water or process heat at intermediate temperatures, i.e. 80 to 180 C, where flat plate collectors are not effective, and for which there are a number of industrial, domestic and rural applications. This paper studies the potential applications of this technology and presents case studies to prove its feasibility.
متن کاملEnergy Consumption and Heat Storage in a Solar Greenhouse: Artificial Neural Network Method
In this study, the performance of a solar greenhouse heating system equipped with a linear parabolic concentrator and a dual-purpose flat plate solar collector was investigated using the Artificial Neural Network (ANN) method. The heat required for the greenhouse at night hours was supplied by the heat stored in the storage tank by the solar system during the sunshine time and an auxiliary he...
متن کاملHigh Temperature Metal Hydrides as Heat Storage Materials for Solar and Related Applications
For the continuous production of electricity with solar heat power plants the storage of heat at a temperature level around 400 degrees C is essential. High temperature metal hydrides offer high heat storage capacities around this temperature. Based on Mg-compounds, these hydrides are in principle low-cost materials with excellent cycling stability. Relevant properties of these hydrides and the...
متن کاملNumerical Simulation of the Freezing Process in Geothermal Boreholes Using Solar Heat Injection
Ground thermal energy as a clean and sustainable energy source has received significant attention lately. Several strategies and hybrid configurations have been proposed to harvest geothermal energy for air conditioning and industrial purposes. The possibility of moist soil freezing in the vicinity of borehole tubes is known to be the source of several benefits and difficulties. The high storag...
متن کاملNumerical Modelling of Solar Heat Storage Using Large Arrays of Borehole Heat Exchangers
The storage of surplus heat in the underground and retrieval when required is a promising method for optimizing the energy efficiency of new housing estates. A new approach for the coupled numerical modelling of such problems will be presented. Here, the energy simulation software TRNSYS is directly coupled with the finite element subsurface flow and transport simulation software FEFLOW. This w...
